Mining of Iron Ores – IspatGuru

The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO (OH)), limonite (FeO (OH).n (H2O)) or siderite (FeCO3). The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps.

Iron Ore Mining | Techniques | Metal Extraction

Haematite and magnetite are the most commonly found iron ore minerals. The smelting process allows the iron ore to be heated with carbon. The carbon combines with the oxygen and carries it away, leaving behind iron. Blast furnaces are so hot which is why they melt the iron, and drain it off to be poured into moulds to form bars, called ingots.

Iron ore - Wikipedia

Metallic iron is virtually unknown on the surface of the Earth except as iron-nickel alloys from meteorites and very rare forms of deep mantle xenoliths. Some iron meteorites are thought to have originated from accreted bodies 1,000 km in diameter or larger. The origin of iron can be ultimately traced to formation through nuclear fusion in stars and most of the iron is thought to have originated in dying stars that are large enough to collapse or explode as supernovae. Although iron is the fourth-most abundant element i…
